A two year field trial was conducted to study the influence of corm size and planting geometry on growth flowering and corm production in gladiolus cv. White Prosperity. Three corm sizes (4.1–4.5,4.6–5.0 and 5.1–5.5 cm dia) and three spacings (10 × 20; 15 × 20 and 20 × 20 cm were tested in RBD replicated thrice. Data revealed that the plant height, number of leaves per plant, number of days taken for spike emergence, spike length, number of florets per spike, floret diameter and number, weight and size of corm and cormels produced were significantly improved in the largest corm size (5.1–5.5 dia.). Wider plant spacing (20 × 20 cm) also improved growth, flowering, corm and cormel production parameters, during both the years of study.
